名词性从句缺成份和不缺成分时的连接词，简洁点

一、缺成分用代词性连接：词.what,whatever,who,whoever,which,whichever,whom,whomever.
二、不缺成分用代词性连接词：when,whenever,where,wherever,that,however,how.
具体需要哪个看情况。

名词性从句是英语三大从句之一。包括四个分支：主语从句、宾语从句、表语从句和同位语从句。既然是复合句，也就是由两者或两者以上的句子复合而成。两句话合二为一的时候需要一个连接词。
最常见的连接词是that在宾语从句中的运用，如：I know that you will come. 句中的that 就是连接词，作用就是连接主句和从句，不充当成分也没有含义，只起风向标的作用，告诉你接下来的部分是一个整体，及that you will come 充当know 的宾语。
whether和if 也是引导名词性从句的连词，与that相同的地方是也不充当从句中的成分，但是是有含义的，“是否”。通常用于有疑问的句子，确定性。我们把that,whether, 和if 称为名词性从句连接词里的“3”。
名词性从句连接词里的“4”：where, when, why, how。此时从句中主谓宾这种主要成分都是不缺少的，缺少的是状语部分，如：I want to go to Walmart, but I don’t know_____ it is. 此时填where，缺少地点。
名词性从句连接词里的“5”：what,who, whom, which, whose. 缺成分指物用what；缺成分指人用who。
如：______ doesn’t does kill you makes you stronger. 填what 指事物。I don’tknow _____ took it away. 填who 指人。which 和 whose 后面通常还需接一个名词，如：I don’t know whichone I should buy. I dont know whosebook it is.
变体部分：whatever，however等相当于no matter what，no matterhow，如：I will do _____ makes her happy. 填whatever。
